¿ªÔÆÌåÓý? I suspect you¡¯ve stumbled over a bug, or unintended consequence. ??? ? The ¡°identify decoder¡± code has found it¡¯s a Hornby, and is trying to identify which TTS sound decoder might be fitted (CV159).?? But, if the decoder doesn¡¯t reply to CV159 (I suspect some more basic, perhaps older, Hornby decoders don¡¯t), then there is going to be an error. ? So, for your side, my suggestion is that you do as you did - ?manually find the decoder type (rather than ¡°read type from loco¡±, go down the list of makers, expand Hornby, and pick the decoder you think is in the loco).??? With other brands of decoder ¡°Read type from decoder¡± should be fine.? ? ? For the software development side -? there is code to identify TTS decoders automatically, ?can it be modified so that a ¡°no loco detected¡± means it stops trying CV159 and decides it must be one of the other Hornby decoders ?????? Or, is a decision between automatically identifying TTS types (really useful to a lot of TTS users) and thus will fail on some other Hornby decoders, or does the automatic TTS identification have to be removed ??? ? ? ? -?????????

I¡¯ve just bought an old SprogII and installed the latest software on a laptop running Windows 7. 2.?????? Borrowed a DCC loco from a friend and checked that it ran under throttle. (Not necessary, but it proved the loco works under my DCC). 3.?????? Then clicked ¡®New Loco¡¯ on menu and ¡¯Read type from decoder¡¯ 4.?????? Messages at bottom report looking at CV8, then 7 then 159. Loco juddered as the decoder was read. Then ¡®Stopping due to error: No locomotive detected (301)¡¯ reported. 5.?????? So repeated step 4 with the Sprog Command Monitor opened. This showed: cmd: "C 0008" rep: "= h30 P> " cmd: "C 0007" rep: "= h83 P> " cmd: "C 0159" rep: "= No Ack P> " ? So the decoder was responding with the make of decoder (Manufacturer number 48, hexadecimal 30, Hornby) and the version 131. But, not finding CV 159, gave up. ? (If you can¡¯t carry out this step, go to step 6 and make a best guess) 6.?????? Chose the best guess Hornby decoder from the list and the ¡®Create Basic Roster Entry¡¯ box appeared. Entered the Roster ID to identify the loco. Clicked ¡®read¡¯ to identify the current address of the decoder (3 for a new decoder). 7.?????? Clicked ¡®Open Comprehensive Programmer¡¯. Entered the details for the roster. 8.?????? Clicked the CVs tab. Clicked the ¡®Read full sheet¡¯ button. The state of some CVs changed to ¡®Read¡¯. (Some CVs may remain yellow and some go red, if that CV doesn¡¯t exist for your decoder.) 9.?????? I didn¡¯t want to change the active address of my friend¡¯s loco, but this should be possible by typing the new number into CV1 and clicking ¡®Write¡¯. 10.?? Closed the window, Saving if requested. 11?? Chose the new loco in the roster. Selected it and chose ¡®Throttle¡¯. 12.?? In the address panel, clicked the ¡®No loco selected¡¯ box and chose the loco. 13.?? Hopefully it should work for you... |
